Established by the Jinwei Group, which boasts a pedigree dating back to 1979 (established with over 40 years of pioneering history in northern China), Kingflex Insulation Co., Ltd. stands as an industrial force in thermal conservation technology. Located in Dacheng, China—widely recognized as the capital of green-building materials—we operate as a specialized manufacturing and trading combo.
Our core philosophy centers on energy efficiency, consumption reduction, and technological stewardship. We provide fully integrated systems across consultation, custom material R&D, precision manufacturing, and installation guidance. As an authorized supplier across major sectors, our high-density rubber foam and rock wool materials provide essential heat-loss mitigation, anti-condensation control, and acoustic damping to global infrastructure projects.
How molecular structures and vulcanization controls dictate thermal performance and durability in extreme environments.
Our formulation leverages a high-grade Nitrile-Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC) compound. This blend enhances chemical resistance, limits gas permeability, and delivers consistent elastomeric flexibility. This guarantees resistance to mechanical stress and thermal fatigue from -40°C up to 105°C.
Through our continuous horizontal foaming process, we yield an average closed-cell ratio exceeding 98%. This dense cell alignment traps tiny air packets within, maintaining low thermal conductivity, while acting as an integrated, continuous vapor barrier that resists moisture ingress.
Integrated inorganic fire-retardants form a carbonaceous protective layer when exposed to heat. The self-extinguishing chemistry minimizes heat release and flame propagation, complying with building safety codes including BS 476, CE, REACH, ROHS, UL94, and ASTM.
With eight full-time R&D material scientists and testing specialists on-site, Kingflex targets breakthroughs in lower-density elastomeric materials. Reducing raw density down to 40 kg/m³ while maintaining a high elastic recovery rate of over 80% represents an engineering threshold that lowers transportation overheads and installation handling weight.
Additionally, our future product pipeline targets high-performance aerogel-hybrid foams to address challenges in Ultra-Low Temperature (ULT) cryogenic facilities and liquefied natural gas (LNG) processing facilities, preventing thermal bridging and condensation in cold climates.
From building HVAC systems to petrochemical processing pipelines, our solutions are engineered for safety and thermal efficiency.
Mitigates condensation on chilled water pipes and air ducts, preventing mold growth and ensuring high indoor air quality (IAQ). Ideally suited for hotels, commercial retail complexes, airports, and medical facilities.
Advanced elastomer blends (such as Alkadiene and Dienes Rubber Foam) maintain flexibility at temperatures below -180°C. Essential for LNG ship loading docks, liquid nitrogen storage, and cold-box piping systems.
Complementary systems using rock wool blankets protect steam pipes, power generation turbines, and chemical storage reservoirs. Deliver mechanical resilience under thermal expansion and vibration.

Operating out of our digitalized production base in Dacheng, China, we mitigate macro supply chain volatility through deep raw material integration and high process automation. Powered by 5 continuous extrusion and vulcanization lines, Kingflex guarantees a steady supply of elastomeric NBR/PVC foams, rock wool, and sound isolation materials.
By monitoring vulcanization temperatures and foam density in real-time, our manufacturing line yields uniform structural properties. Global infrastructure managers, logistics teams, and procurement coordinators rely on us for consistent bulk quantities, stable lead times, and direct shipping logistics.
A collaborative team of engineers, sales specialists, and technicians backed by rigorous international standard certifications.
Our workforce forms the cornerstone of Kingflex's engineering reputation. Our team consists of 230 production personnel, 8 specialized R&D chemical engineers, and 6 international technical sales professionals. Our collaborative efforts focus on delivering first-class service to clients across regional customs borders and complex regulatory zones.
This commitment is supported by our international certifications. Every batch of elastomeric foam, rock wool, and adhesive compound leaves our warehouse backed by quality compliance credentials, ensuring smooth site entry for demanding construction works.
Ensuring streamlined global logistics, rigorous QA protocols, and structured service level agreements (SLAs) for international procurement.
Large infrastructure projects require flexible shipping timelines and packaging formats. Kingflex provides compressed roll structures, vacuum-sealed tubing packages, and robust poly-wrap bags. This ensures that physical products are protected against container humidity, salt-spray oxidation during marine transport, and mechanical abrasions during transit.
We work directly with reliable global freight forwarders to provide FOB, CIF, DDP, and DAP terms. Our team handles complete customs clearance paperwork, including origin certifications, standard commercial documentation, and compliance certificates, ensuring smooth entry at destination ports.
Our plant supports customized engineering designs. If a project requires specific dimensions, non-standard interior diameters (ID), colored protective coatings (e.g., green, red, or blue identifiers for plumbing systems), or aluminum foil backing, our engineering team can adapt the production setup to match.
We supply detailed mechanical drawings, performance testing metrics, and pre-production samples. This ensures the custom insulation fits complex HVAC duct configurations, large storage tanks, and pre-insulated pipelines without issues.
